Question

Would this program compile run? If not, why; if yes: what would be the output? public class ConstChaini { public static void main(String [] args){ new SubClass(); System.out.println(); new SubClass(1); } class SuperClass{ public SuperClass(){ System.out.print(-4-); } public SuperClass(int i){ System.out.print("8"); } } class SubClass extends SuperClass( public SubClass()( this(1e); System.out.print(C"); } public SubClass(int i){ super(i); System.out.print("D"); }

Answer 1

Answer:

Check the explanation

Explanation:

// Code to copy

public class ConstChain1 {

public static void main(String[] args)

{

new SubClass();

System.out.println();

new SubClass(1);

}

}

class SuperClass{

public SuperClass() {

System.out.println("D");

}

public SuperClass(int i) {

System.out.println("C");

}

}

class SubClass extends SuperClass{

public SubClass() {

this(10);

System.out.println("B");

}

public SubClass(int i) {

super(i);

System.out.println("A");

}

}

Explanation:

Now each time when a object of a subclass is been created it's super class constructor will be executed first then only subclass object is created by executing it's constructor.
